Wildman 5" Jayhawk Build Thread

[kjhambrick]

Has to be Bong with the pond!

Shucks, what with all the trees and ponds, it could be Texas

Justin --

Your Jayhawk is beautiful coming down under that Valkrie Recovery Systems - 8-foot Explorer Chute !

Didn't you also get one of the Valkrie Recovery Systems - Explorer Drogue Chutes too ?

Thoughts ?

Thanks for this Thread !

-- kjh( and what's not to like about the flamey end of that K2050ST )

Excellent job, Justin! And Adrian is indeed looking good.

Strange seeing open water at Bong in February.

Any chance of getting the 3d print file for the wiring tunnel posted? I have a 4" and 5.5" Polecat Jayhawk that I been procastinating finishing for far too long...

My pics were ok, @KevinH pics are off the chain!

That parachute is insane. I love that paint scheme you decided to go with also!

The shovel is a Tripoli thing. NAR only has a budget for a stomped out piece of sheet metal.

And the Jayhawk under the chute reminds me of a baby shark on a line

Very cool

Nice recovery deployment! I have been told that one of the dangers with large jayhawks is getting it tangled up with all the finage.

How did you cut the fiberglass tube for the wiring tunnel in half?

 

[NTP2]

So cool!!

Not that I am aware of or seen.... yet?

Fiberglass cut off wheel on a Dremel moto-tool with flexible extension. I first used aluminum angle iron to scribe lines down the length on both sides of the 38mm tube.

Those forward fins make it look like it has a 'permanent' vapor cone around the nose cone!

..see kids 'cool looking rockets' can also be Badass rockets too!

Great flight pics!
That chute is pretty spectacular. Would be interested in your post-burn weight and corresponding main descent rate if possible to share.

Weight is easy, I can get to that this week. Main descent rate can be pulled off the RRC3's in time. Stupid busy at work the last couple weeks!

Cool. Getting ready to work on chute options for a new project - appreciate your data whenever available, no rush.

(work always slowing down the fun stuff ).

Gluing and screwing the wings and winglets is a bit of a task, but got one of them done at least.

I couldn't pick it up from your pictures or descriptions. What did you use for nuts on the bolts you bolted the outboard winglets to the L bracket aluminum (both through the fin and through the winglets? Thanks!

Short answer is (3) 8-32 PEM Nuts on the "inside edge" towards the wiring tunnel on each wing.

Working towards flight 2. Adding (2) .357 case line cutters, and adding drogue . So far so good on the line cutters, 3 tests, 3 successes.

what captures the silver cutter? are they a one-use item?

They can be single use, but I'll likely drill another hole and connect it off via paracord to the Kevlar recovery harness.

Trying to get more sanding and filler done, working towards getting primer on the pig.

 

[rfjustin]

Couldn't help it, had to spot on some primer to see a little more detail.

Never really liked the Jayhawk, but you are making it look good!!!

Amazing rocket!

I would have left the metal tip unpainted, though...
